Applieatiea med september 25, `1912. serial No. 722,225.

To all 'whom may concern,

Be it known that I, "WiLLIaM HENRY WVIL-` son, a citizen of the United:States, and` a resident `ot New Bedford, inithe `countyot i jBristol andState ofMassachusetts, have invented` a new and Improved Loom-Shuttle,

of which the following; is a full, clear, and

exact description. e

The invention relatesto `self-vthreading1 shuttles, such, for instance,as` shown and described `in `thel Letters `Patent of the; United States,No. 987,524,granted ltomew March 21, 1911.

The object of the present invention` is to` provide a new andimprovedloom `shuttle arranged` to permit` of conveniently and securelyfastening the threadfretaining;de` vice in place in the shuttle body,`and to prevent the thread fromzcatching or ballooning. 1

For the purpose mentioned, use is made of a thread-retainlng deviceformed from a single piece of sheet metal and comprisingl a baseextending transversely in the `shuttle body, thread-guide plates risingEfrom the front and rear `edges of the said base and having their inneredges overlapping` in: spaced relation, anda hook extending `for` wardlyfrom the, inner end 0f thefront thread guide plate, the bottomedge ofthe,hook being above the plane of the `said basel Use is also made oftongues extending longi` tudinally from the outer edges of the thread;`guide plates and engaging longitudinal` grooves in the shuttle body, thesaid tongues terminating in outwardly-bent points iembedded in theshuttle body; w v

A practical embodiment `of the ,invention is represented in the`accompanying draw` ings forming a part of this specification, in whichsimilar characters iof `reference indicate corresponding parts in allthe views.

Figure 1 is a plan View 0f lthe delivery end of the improved `loomshuttle;` Fig. 2

is a sectional plan view of `the same; Fig.`3

is a cross section` of the same on the line 3-3 of Fig. 2; and FigAejlsaperspective` view of the thread-retaining device.

i The body A `of the` `shuttle isi `provided with the usual elongated sindleiopening B? `in which extends the spind e C carryingthe bobbinDfrom which unwinds the thread E adapted to passV through a delivery eyeFsin the side of the shuttle body Aa e In the top of the shuttle body Aadjacent: the delivery end Eis a substantially vertical opening` Gextending about half wayl through the shut tle body: (see Fig.` 3) andconnected to the recess Baby a throat H. The upper end of` the opening`G and the sides of the throat H are preferably beveled and cut awaysoas to avoid sharp edges which might cut or: `sever the thread. Thedelivery end ofthe shuttle `body `is further provided with the usualdiagonal slot I extending downwardly in depth to approximately thebottom ofthe recessG, and a horizontal slot (not shown) connects thelower `orl innermost portion of the slotI with the transverse deliveryeye Fl` In threading `the shuttle the thread El is dropped through thethroat I-I, the recess; G,

the s lot I andits connecting horizontal slot and 1s then lbroughtintothe delivery eyeF soithat the thread `extendsout through one side ofthe latter, as plainly indicated` in: Figs. l and2.` The shuttle so fardescribed is similar to the one referred to inthe patent abovementioned.`

For `preventing a loop in the thread from r1s1ng `or balloonlng `outthrough the slot I,

use is madet of a, thread-retaining device arranged within the recessoropening G, so`

SOI

constructed` as to facilitate the entrance `of the thread but to preventits return movement. The thread-retaining device is formed from a singlepiece `of sheet metal` bent `to provide a base J, from the rear andfronte: edges of which rise thread guide plates J1`,` Jhaving theirinner edges overlapping in; spaced relation, as plainlyindicated in thel drawings.

thread LEcan readily pass under the `hook Je; i i In order tosecurelyhold the thread-re` body A, the `following arrangement is made:The outer edges of the thread guide plates J1 and J2 fit in verticalgrooves G1, and` from the outer edges of the said plates J1,

J 2 extend integral, rearwardly-bent p'arallel tongues J t engaginglongitudinal grooves e G2 formed in the side walls of the `recess G landleading to the vertical grooves G1. The tongues Jt terminate inoutwardlybent points J5 adapted to be driven iintol a recess G3 formed1n theside Walls of the` l taining device; in position` in the shnttle;

thread guide plates J1, J 2, are held against Y firmlyY fasten ythethread-retaining ydevice Vin ymetal and comprising a` base extendingVare suiciently resilient to permit of readily inthe manner describedrequires no screws,
